In The Crown Tundra players are forced to choose between Regieleki or Regidrago, and Spectrier or Glastrier. This limits your choices of which legendary Pokemon you can get in your game. But what if I told you it is possible to get all these Pokemon in one game without having to trade anyone?
This is made possible by the Nintendo Switch profile system. Be aware, that you must have Nintendo Switch Online and access to Pokemon Bank in order to do this.
First you will want to add a new profile to your Nintendo Switch. To make a new profile, go to system settings > Users > Add User. If you already have an extra profile laying around, you can skip this step.
Once you have a new user, open up Pokemon Sword and Shield and start the game with your new profile. Now you will have to play through the start of the game until you get access to the wild area. After that you can immediately go to the Crown Tundra if you want to.
Lose to Peoni and play through the Dynamax Adventure. Even though you have no gym badges, you can still catch any Pokemon in a Dynamax Adventure and choose one to keep. Go through a few Dynamax adventures to get a team of level 65-75 Pokemon that will obey you. This will help you in the next step.
After finishing the Dynamax adventures you are able to play through the storylines in the Crown Tundra. But you cannot catch any Pokemon since they are “too strong.” This includes Regirock, Registeel, Regice, Regieleki and Regidrago. And Glastrier and Spectrier are unobtainable until you become Champion, as Calyrex will not battle you before that. So you will have to beat all the gyms in Pokemon Sword and Shield and become the Champion to catch them.
Luckily the Pokemon in the Dynamax adventures do not have gym badge requirements. So take the Pokemon you captured through these adventures to breeze your way through the game. To make things faster, I suggest turning off battle effects, changing battle style to set, and turning Skip Movies on in the settings. Beat the game with your powerful Pokemon and then return to the Crown Tundra.
Now you can finish the storylines to get the Pokemon you want. When you get to the Regieleki or Regidrago temple, choose the one you did not capture in your main game. Do the same when given the choice on having Spectrier or Glastrier. Make sure to separate Calyrex from Spectrier or Glastrier, as the combined form cannot be put into Pokemon Bank.
Once you have the Pokemon you want, make sure they are inside your boxes. Then save the game and close it.
The next step is to open Pokemon Bank, but make sure to open it with the profile your main save is connected to. Select Pokemon on the first page, and on the next page you can actually change the profile. Do this by pressing A with your name selected, and the game will ask you if you want to change profiles. Now you can select the second profile you made, and then select Pokemon Sword and Shield.
Pokemon Bank will pull up the boxes for your second profile, but the bank boxes will be the ones from your main account. Place Regieleki/Regidrago and Spectrier/Glastrier into the bank, then save and exit.
You will be put back at the home page of Pokemon Home. Once again select Pokemon, then change the user back to your main profile. Go into Pokemon Sword and Shield and you will see the Pokemon you just deposited, sitting in the bank. Place these into your main game, then save and exit.
Now you can start up Pokemon Sword/Shield on your main profile. Look in your box and you will now have Regieleki, Regidrago, Spectrier, and Glastrier from The Crown Tundra!
